18 East 21st Street, Brooklyn, NY 11226

The building at 18 East 21st Street in Flatbush, a 6-story New Law Tenement constructed in 1927 and currently owned by Yida Stern, has experienced several concerning maintenance issues in recent months. Most notably, there have been recurring problems with mold and rodent infestations, with multiple complaints filed through 311 and HPD between March and May 2025. The property has also faced challenges with heat and hot water distribution, as evidenced by multiple complaints in March-April 2025, though some of these conditions were reportedly resolved during inspections.

A series of rodent inspections conducted from September 2024 to July 2025 indicate ongoing vermin activity, with bait applied regularly. The building dedicated significant resources to address various maintenance issues in 2024-2025, including violations related to apartment E2 where multiple problems were identified through a December 2024 inspection. These included issues with carbon monoxide detectors, floor conditions, pest infestations (roaches and mice), and various maintenance needs such as door repairs and problems with the intercom system.

While these violations were certified as corrected between January and March 2025, there was one open violation regarding an unauthorized alteration involving a full-height partition. Historical records show past concerns regarding elevator service, after-hours work, and illegal conversions, though these complaints were typically investigated with no violations found. The building's management has demonstrated some responsiveness to identified issues, as evidenced by the closure of various complaints, but the persistence of certain problems, particularly relating to pests and mold, remains a notable concern.
